IMPROVEMENT IN CHART-HOLDERS.

Specification forming part of Letters Patent No. 119,054, datedSeptember 19, 1871.

To all whom it may concern.-

Be it known that I, DANIEL SHRYOGK, of Hannibal, Marion county,Missouri, have invented a new and useful Device for Hanging Charts, &e.,of which the following is a specification:

This invention relates to a novel and convenient arrangement of swingingracks or brackets for the support and display of a series of charts,maps, or other printed or pictorial representations.

The accompanying drawing is a perspective View of a series of chartsarranged and supported on my plan. 7

A and B- eonstitute the vertical and horizontal portions of a bracket,of which parts the vertical portion A is attached to a wall or otherstationary or convenient object; and the portion B earries a bolt orpivot, 0', for the eyes D or perforated extremities of a series of rods,D E, from "which the charts F or other printed or pictorial Projectinghorizontally sheets are suspended. or nearly so from the portion A is awire loop or staple, G, whose part most distant from A is curvedslightly upward. The ends of this staple,- which enter grooves a a inthe part A, are secured firmly therein by a pin, H, but can be withdrawn by removal of the pin. Strung or rove upon the staple G are aseries of rings, I, from which as many wires J extend obliquely and tarminate in hooks K, that engage in eyes L upon the rods E, so as tosupport the latter in a horizontal position under all circumstances. Theeyes D of all the rods except the middle one, while all of them arehorizontal, extend laterally and downwarda greateror less distance,which distance is greatest for those nearest the outside, so as to bringall of the rods E into the represented compact and parallel positionwith respect to each other when folded back in either direction. Inarranging the eyes upon the pivot an outside one is first appliedsuperimposed by that on the opposite side-and so on, alternately, firston one side and then on the other side,

until all are applied. By this alternate application of them the movingof one red does not at feet that next to it, and, consequently, all therods and their suspended sheets in rear of the one moved remainundisturbed.

The sheets of music, charts, or other representations may be attachedback to back so as to give two subjects to each sheet, and each sheetbeing attached by its upper edge to a rod the several sheets arearranged in proper order, and their eyes are arranged alternately bysuperposition upon the pivot-bolt, and their rings are rove in properrelative order upon the staple, which is then secured in the postA, asabove explained. When not desired for immediate use the entire set maybe folded either to the right or to the left against the wall 5 butshould it be desired to examine or expose any chart in rear of the frontone,.it is readily accomplished for the front side of such chart byfolding to the right or left, as the case maybe, all in front of it, andfor the rear of such chart, folding also the chart itself; it beingobservable that the obverse or reverse ofany sheet can beinstantaneously exposed by turning or folding either to the right or tothe left.

The effect of the upturned and curved staple in conjunction with thewires J is to support each and every sheet at its proper elevation inevery position at which it can be placed.

I claim herein as new and of my invention l. The described arrangementof rods E, eyes D, oblique wires J, and staple G, for the purpose setforth.

2. In the described combination with the above, the described mode ofsecuring the staple G in the post. 7

In testimony of which invention I hereunto set my hand.

DANIEL SHRYOOK.
